LOADING APPARATUS.

Specification of Letters Patent.

Patented Dec. 1, 1914.

. Application filed May 27, 1912. Serial No. 699,885.

manure it is to be understood that I am not to be limited to such use alone but can adapt it for gravel, etc., by merely changing the fork to a shovel or the like.

The object of this invention is the provision of a loading apparatus for gathering manure or the like and elevating the same into the box of a wagon wherein it may be transported to any desired locality.

Another object of this invention is the provision of a device such as described employing an elevated track upon WlllCll 1s located a carriage equipped with means for locking the same against displacement and for tripping the fork suspended therebcneath.

A further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and efficient in use and readily operated.

lVith the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of my invention; Fig. 2 is a top plan view thereof; Fig. 3 is an end view thereof, and Fig. 4 is an enlarged sectional view taken on the line aa of Fig. 2.

Referring to the accompanying drawings by similar characters of reference, the numeral 10 designates generally my improved conveyer which comprises a supporting frame 11 consisting of a pair of U-shaped supports 12 connected by a track 13 which is circular in cross section and reduced at its opposite ends to pass through apertures formed in the bight of the supports 12. The terminals of the track 13 are connected to the legs of the supports 12 by any suitable means. A collar 15 is attached to one end of the track 13 in spaced relation to the in. ner side of the adjacent support 12 for a purpose to be later disclosed. A U shaped plate 16 surrounds the track 13 and extends beyond the upper side thereof to produce supports in which are journaled grooved rollers 17 which engage the track and absorb friction upon the longitudinal movement of the car 18 produced by the said plate 1.6 and a pair of hangers lt) and 20 which depend therefrom.

The hangers 19 comprise a pair of bars 21 between which is pivoted a latch 22 which engages the collar 15 and prevents the longitudinal movement of the car upon the track permitting its lateral swinging movement. This latch 22 is normally forced to engage the said collar by a spring 23. A cable 2k is attached to the lower end of the hanger 19 and passes under a pulley mounted upon a clevis 26, and over a pulley 29 supported by the lower end of the hanger 20, to a pulley 28 secured to one end. of the track 13 and from thence to the operator. A weighted keeper 29 is pivoted between the opposite sides 30 of the hanger 20 and normally engages the cable 2-l holding the same against displacement in the lowering direction.

A plunger 31 is slidable in guides 32 attached to the hanger 20 and plate 16, and is normally held slightly spaced from the keeper 29 by a coil spring 32. The forward end of the plunger is offset as at 33 to contact with the collar 15 and force the said keeper out of engagement with the cable 24 thereby releasing the same.

A bail 34 is attached to the clevis 26 and has pivoted to its opposite ends, a fork 35 or the like. A. shank 36 extends from one end of the fork and has embracing its opposite sides and pivoted thereon an extension 37. The shank 36 is provided with a finger 38 which engages a socket 39 formed in the extension member, in which it is held by connecting pin l0 carried by the forked end of a trip lever 41 pivoted to said extension member. A flexible member L2 is attached to the free end of the trip lever ll to provide a means of operating the same. The fork 35 is suitably b aeed as at it and provided with rearwardly extending handles i5.

The device is operated as follows: When the fork is positioned as shown in Fig. 1,

and filled with hay or the like, the weight of the same causes the extension 37 to en- 5 gage the bail 34-, which retains the fork in a horizontal position, and prevents the undesired dumping of the hay. As the cable is pulled, the slack portion which engages the pulley 25 is decreased, and the fork raised until the same contacts with the latch 22, which releases the car 18. As the cable is then taut, further pull thereon will move the car over the track 13, to the desired point of dumping. When it is desired to dump the contents of the fork, the

cable 412 is given a sharp jerk which releases the extension 37 from the bail 34: and

permits the fork to tilt forwardly, relieving the same of its contents. I

The specific form of fork shown has no bearing on the invention, and it is understood that this is a conventional showing, and that any other type of fork can be substituted for the same.

From the foregoing disclosure, taken in connection with the accompanying drawings, it will be manifest that a loading apparatus is provided for which will fulfil all of the necessary requirements of such a de- 30 vice, it being understood however that various minor changes in the details of construction can be resorted to within the scope of the appended claim without departing from or sacrificing any of the advantages of the invention.

Having thus fully described this invention, what I claim as new and desire to protect by Letters Patent is:

The combination with an elevated track, of a Ushaped plate surrounding the track, grooved rollers journaled upon the, plate and engaging the track, hangers depending from the U-shaped plate, a collar upon the track, a latch pivoted to one hanger for engagement with the collar, a pulley mounted upon the other hanger, a cable attached to the, first hanger and passing over said pulley, a fork supported by the cable, a keeper pivoted to the second named hanger and engaging the cable, and a spring actuated plunger slidable upon the U-shaped plate and engaging the keeper for contact with the collar.

In testimony whereof I afiix my signature in presence of two Witnesses.
